IMPROVEMENT IN HEARTH-PLATES.

Specification forming part of Letters Patent No. 153,574., dated July28, 1874; application filed June 17, 1874.

To all whom it may concern:

Be it known that I, RUFUS J. KING, of Dayton, in the county ofMontgomery and State of Ohio, have invented a new and useful Improvementin Hearth-Plates; and I do hereby declare that the following is a fulland exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention relates to that class of stoves in which the draft isregulated by means of the hearth-plate; and consists, substantially, ofa hearth-plate hinged on a lateral pivot, which is free to slidebackward and forward in a slot, and swing around upon its hinge, whendesired. 7

Figure 1 represents a perspective view of an ordinary cooking-stoveprovided with my improved hearth-plate. Fig. 2 represents the stovehearth with the plate turned on its pivot to allow free access to theash-pit. Fig. 3 represents the plate detached to show its pivot and theslot in the hearth beneath in which it works.

My improvement provides the means of swinging the hearth-plate out ofthe way, so as to give access to the ash-pit, and also admits of theplate being uniformly drawn out to any desired extent to regulate thedraft. The swinging action may be availed of when the hearth is drawnout.

In the aceompanyin g drawings, A represents my improved hearth-plate,which is of the ordinary shape, but has a lateral projection, B, to theunder side of which is cast or otherwise fastened a pivot, 0, having acatch or detent near its lower end. The function of the latter is tohold the plate securely upon the hearth when it is swung around upon itspivot, as denoted in Fig. 2. The slot D, in which the pivot 0 works, ismade through the hearth at the side of the ash-pit.

This slot may be of any desired length, but

of a width just suflicient to allow the introduction of the pivot G. Theprojection on pivot G will only enter the slot when the plate A is in aposition parallel with the front of the stove, as in Fig. 1. When theplate Ais turned upon its pivot O, the detent works under the hearth,and holds the plate securely.

The advantages to be gained by my invention, as above indicated, aretwofold, viz: A uniform draft can be obtained by sliding the plateoutward, which could not be done were it simply hinged without beingcapable of sliding, and the plate is free to be turned so as tocompletely expose the ash-pit, and at the same time it will be securelyheld fast to the hearth, thus avoiding the necessity of handling andremoving it.

Having fully described my invention, I claim and desire to secure byLetters Patent- The pivoted sliding hearth-plate A, in combination withthe slotted hearth, substantially as described, for the purposespecified.

RUFUS J. KING.
